could you please explain how to take symmetry boundary condition
The fluid flow and heat transfer simulations have been carried
out using commercial CFD tool, ANSYS CFX 14.5. The
coolant used in the experiments is water and the same is used
in CFD studies for validation and parametric studies. A single
phase laminar fluid flow and heat transfer analysis is carried
out. Continuum flow is assumed inside the micro heat exchanger.
The flow field and heat transfer characteristics through the
micro channel heat sink are obtained by solving the threedimensional
governing equations namely the following: continuity
for conservation of mass, Navier-Stokes equation for
conservation of momentum and energy equation. Fluid
domain of water and solid domain of micro-channel heat sink
are meshed separately and proper interface is defined in
ANSYS CFX Pre for capturing the flow physics. The meshing
of fluid and solid domains is carried out in ICEMCFD tool
using blocking methodology. Only one fluid channel and two
solid domains, each half on either side of the fluid domain,
are considered in the analysis and the entire model with 122
channels is not simulated. Symmetry boundary condition is
applied on either side of the solid domains of the MCHS

You can search in Youtube" on simulation of heat transfer and fluid flow in heat sink using ANSYS FLUENT". You will get the right tutorial which explains step by step procedure from geometry to post processing.
Please note that the tutorial is not prepared by ANSYS.
Hope you get the right tutorial and helpful to you.
